Thehyoid apparatus is the collective term used in veterinary anatomy for the bones which suspend the tongue andlarynx.[1] It consists of pairs of stylohyoid, thyrohyoid, epihyoid and ceratohyoid bones, and a single basihyoid bone.[2] The hyoid apparatus resembles the shape of a trapeze,[3] or a bent letter "H".[4] The basihyoid bone lies within the muscle at the base of the tongue.[1]
In humans, the singlehyoid bone is an equivalent of the hyoid apparatus.[5]
